Filmi is the song tradition of Indian cinema, encompassing Hindi, Tamil, Telugu, Bengali, and other regional film industries. It is built for on-screen storytelling and "playback" singing, where actors lip-sync to pre-recorded vocals. Stylistically, filmi blends raga-informed melodies from Hindustani and Carnatic classical music with Indian folk forms, devotional currents (ghazal, qawwali, bhajan), and an evolving palette of Western popular idioms—big band, jazz, rock, disco, synth-pop, and EDM. Arrangements often feature lush orchestration, prominent melodic hooks, and dramatic modulations, supporting narratives of romance, devotion, comedy, and spectacle. As one of the most-heard musical practices in South Asia and its diaspora, filmi has defined the sound of commercial Indian culture for nearly a century while continually adapting to technology, audience taste, and cross-cultural exchange.

Mollywood is the umbrella term for Malayalam‑language film music from Kerala, India. It blends Indian classical traditions, regional folk idioms, and global popular styles into songs designed for cinema narratives. Classic Mollywood songs draw heavily on Carnatic and Hindustani melodic frameworks (ragas), while also absorbing Kerala folk colors such as devotional and mappila song aesthetics. From the late 20th century onward, arrangers added Western harmony, orchestration, and later electronic production, yielding lush string sections, expressive woodwinds and flutes, and contemporary rhythm sections. Lyrically, Mollywood emphasizes poetic Malayalam—romance, devotion, nature, social reflection—and strong melody-centric writing. The genre is renowned for virtuosic vocal performances and memorable tunes that serve both on-screen storytelling and standalone listening.

Bollywood is the popular film-music tradition associated with Hindi-language cinema from Mumbai, India. It blends raga-based melodies and Hindustani vocalism with Western orchestration, jazz/big-band legacies, pop hooks, disco/funk grooves, rock energy, and contemporary electronic production. Songs are typically designed for on-screen performance and storytelling, featuring lush arrangements, memorable refrains, and emotive playback singing. A common formal scheme is the mukhda (catchy refrain) and antara (stanza/verse) structure, often with instrumental preludes, interludes, and dance breaks. Because it serves narrative and spectacle, Bollywood music ranges widely in mood—from romantic ballads and devotional pieces to high-energy dance numbers—and has continuously absorbed global influences while remaining rooted in Indian melodic and rhythmic aesthetics.

Soundtrack is music created to accompany and enhance visual media such as film, television, and video games. It includes original scores (instrumental or vocal music composed specifically for the picture) and, at times, curated compilations of pre-existing songs. Stylistically, soundtrack is a meta-genre that can encompass orchestral symphonic writing, jazz, electronic and synth-driven textures, choral forces, popular song, and experimental sound design. Its defining trait is functional storytelling: themes, motifs, harmony, rhythm, and timbre are shaped by narrative needs, character psychology, pacing, and editing. Common features include leitmotifs for characters or ideas, modular cues that can be edited to picture, dynamic orchestration for dramatic range, and production approaches that sit well under dialogue and sound effects. Because it must synchronize to picture, soundtrack often uses clear dramatic arcs, tempo maps, and hit points.

Electronic is a broad umbrella genre defined by the primary use of electronically generated or electronically processed sound. It encompasses music made with synthesizers, drum machines, samplers, computers, and studio/tape techniques, as well as electroacoustic manipulation of recorded or synthetic sources. The genre ranges from academic and experimental traditions to popular and dance-oriented forms. While its sonic palette is rooted in electricity and circuitry, its aesthetics span minimal and textural explorations, structured song forms, and beat-driven club permutations. Electronic emphasizes sound design, timbre, and studio-as-instrument practices as much as melody and harmony.
